Electronic stabilisation
control (ESC)
Description
The electronic stabilisation control (ESC) increa­
ses the car's stability. It reduces the tendency to
skid and improves the stability and roadholding
of the vehicle. The ESC detects critical handling
situations, such as understeer, oversteer and

wheelspin
on the driven wheels. It stabilises the
vehicle by braking individual wheels or by reduc­
ing the engine torque. The indicator
lamp^
in
the instrument cluster starts flashing as soon as
the ESC intervenes.
The following systems are integrated in the ESC:
Anti-lock brake system (ABS)
ABS prevents the wheels from locking up under
braking until the vehicle has reached a virtual

standstill.
You can continue to steer the vehicle
even when the brakes are on
full.
Keep your foot
on the brake pedal and do not pump the brakes.
You will feel the brake pedal puLsate while the
anti-lock brake system is working.
Brake assist system
The brake assist system can shorten the braking
distance. The braking force is automatically boos­
ted if
you
press the brake pedal quickly in an
emergency. You must keep pressing the brake
pedal until the danger has passed. On
vehides

with adaptive cruise control*, the response of the
brake assist system will be more sensitive if you
are too close to the vehicLe in front.
Traction control system (ASR)
In the event of
wheelspin,
the traction control
system reduces the engine torque to match the
amount of grip available. This helps the car to
start moving, accelerate or climb a gradient.
Electronic differential lock (EDL)
When the EDL detects wheelspin, it brakes the
spinning wheel and directs the power to the
oth­

er driven wheel (or wheels on quattro* versions).
This function is not available at high speeds.
To prevent the disc brake of the braked wheel
from overheating, the EDL cuts out automatically
if subjected to excessive loads. The vehicLe can
still be driven. The EDL will switch on again auto­
matically when the brake has cooled down.
Steering recommendation
The ESC helps to stabilise the vehicle by changing
the steering wheel torque.
Trailer stabilisation system
Applies to: vehicles with trailer stabilisation system
Trailers have a tendency to sway. If the
ESC
de­
tects that the trailer is swaying and this is affect­
ing the towing vehicLe, it will automatically brake
the vehicle in order to stabilise the trailer

^>page
97.
Selective wheel torque control
Selective wheel torque control intervenes when
cornering by braking the wheel(s) on the inside of
the bend individually as required. This enables
precision cornering.
Multicollision brake assist system
The "multicollision brake assist system" can help
to reduce the risk of skidding and further
colli­

sions during an accident. If the airbag control
unit detects that
a
collision has taken place up­
wards of
a
certain speed, the vehicle is braked by
the
ESC.

The vehicle will not be braked automatically if:
- the driver presses the accelerator,
- or the
ESC,
the brake system or the vehicle's
electrical system are not fully functional.
WARNING
- The grip provided by the ESC and the inte­
grated systems is still subject to the physi­
cal limits of adhesion. Always bear this in

mind,
especially on wet or sLippery roads. If
you notice the systems cutting in, you
should reduce your speed immediately to
suit the road and traffic conditions. Do not

let
the extra safety provided tempt you into
taking any risks when driving - this can
cause accidents.
145

Intelligent technology
Remember that the accident risk always in­
creases
if
you
drive fast, especially
in
cor­
ners
or
on a wet
or
slippery
road,
or if
you
follow too close behind the vehicle in front
of
you.
Please bear
in
mind that even
the

ESC
and
the
integrated systems cannot
compensate
for
the increased accident risk.
When accelerating
on
a uniformly slippery
surface
(for
instance
all
four wheels on
ice

or snow), press the accelerator gradually
and carefully. The driven wheels may other­
wise start
to
spin
(in
spite
of
the integrated
control systems), which would impair the
car's stability and could lead
to
an accident.
© Note
The ABS and ASR systems can only work
properly
if
a 11
four tyres have a similar de­
gree
of
wear. Any differences
in the
rolling
radius
of
the tyres can cause the system
to

reduce engine power when this
is not
de­

sired.

The systems can make noises when they in­
tervene.

WARNING
You should switch on the off-road mode or
switch off the ESC/traction control system
(ASR) only if your driving ability and the traf­
fic conditions allow you to do so safely -
dan­

ger of skidding!
- The stabilising function is restricted when
off-road mode is switched on. The driven
wheels may start to
spin,
causing the
vehi­

cle to lose grip, in particular on slippery or
wet roads.
- When the ESC/traction control system
(ASR) is switched off, the vehicle will not be

stabilised.

Brakes
New brake pads
New brake pads do not give full braking effect for
the first 400 km, they must first be "bedded in".
However, you can compensate for the slightly re­
duced braking effect by applying more pressure
on the brake pedal. Avoid placing a heavy load on
the brakes during the running-in period.
Wear
The rate of wear on the brake pads depends a
great deal on how you drive and the conditions in
which the vehicLe is operated. Negative factors

are,
for instance, city traffic, frequent short trips
or hard driving with abrupt starts and stops.
Noises
Brake noise may develop in certain situations, de­
pending on the speed, braking force and ambient
conditions (such as temperature and relative hu­
midity).
Effect of moisture and salt
In certain conditions, such as in heavy
rain,
early
morning dew, or after washing the car or driving
through water, the full braking effect can be de­
layed by moisture (or in winter by ice) on the
discs and brake pads. The brakes should be
< "dried" by pressing the pedal to restore full brak-

R
ing effect.
When you are driving at higher speeds with the
windscreen wipers on, the brake pads are very
briefly brought into contact with the brake discs.
This automatic process which goes unnoticed by
the driver is carried out at regular intervals and is
intended to improve braking response in wet
con­

ditions.
The effectiveness of the brakes can also be
tem­

porarily reduced if the car is driven for some dis­
tance without using the brakes when there is a
lot of salt on the road in winter. The layer of salt
that accumulates on the discs and pads can be
removed with a few cautious brake applications.
Corrosion
There may be a tendency for dirt to build up on
the brake pads and corrosion to form on the discs
if the car is used infrequently, or if
you
only drive
low mileages without using the brakes very

much.

If the brakes are not used frequently, or if corro­
sion has formed on the discs, it is advisable to
clean off the pads and discs by braking firmly a
few times from a moderately high speed
•=> A-

Faults in the brake system
If the brake pedal travel should ever increase
suddenly, this may mean that one of the two
brake circuits has failed. Drive immediately to the
nearest qualified workshop and have the fault

rectified.
On the way to the dealer, be prepared
to use more pressure on the brake pedal and al­
low for longer stopping distances.
Low brake fluid level
Malfunctions can occur in the brake system if the
brake fluid level is too low. The brake fluid level
is monitored electronically.
Brake servo
The brake servo amplifies the pressure you apply
to the brake pedal. It only works when the engine
is running. •

WARNING

- When applying
the
brakes
to
clean
off
de­
posits
on the
pads and discs, select
a
clear,
dry
road.
Be sure
not to
inconvenience
or
en­
danger other road users;
do not
risk an
acci­

dent.
- Never
let the car
coast with
the
engine
switched
off
(this can cause accidents).

(T)
CAUTION

- Never
let the
brakes "drag"
by
leaving your
foot on
the
pedal when you
do not
really
in­

tend
to
brake. This overheats
the
brakes,
re­

sulting
in
longer stopping distances
and

greater wear.
- Before driving down
a
long,
steep gradient,
it
is
advisable
to
reduce speed
and
select
a

lower gear.
In
this way you will make use
of

the engine braking effect and relieve
the

load
on the
brakes.
If
you
still have
to use

the brakes,
it is
better
to
brake firmly
at in­

tervals than
to
apply
the
brakes continuous-

Ly

-
If
the brake servo
is out of
action,
you must
apply considerably more pressure
to the

brake pedal than you normally would.
-
If
you
wish
to
equip
the
car with accessories
such as a front spoiler
or
wheel covers,
it is

important that
the
flow
of air to the
front
wheels
is not
obstructed, otherwise
the

brakes can overheat.

Four-wheel drive
(quattro)
Applies to: vehicles with four-wheel drive

On
quattro models
the
engine power is distrib­
uted
to all
four wheels.
General notes
On four-wheel drive vehicles,
the
engine power
is

distributed
to all
four wheels. The distribution
of

power
is
controlled automatically according
to

your driving style and
the
road conditions. Also
refer
to
^>page
145,
Electronic stabilisation con­
trol
(ESC).

The four-wheel drive
is
specially designed
to

complement
the
superior engine power
of
your

Audi.
This combination gives
the car
exceptional
handling
and
performance capabilities
-
both
on

normal roads and
in
more difficult conditions,
such
as
snow and
ice.
Even
so (or
perhaps espe­
cially
for
this reason),
it is
important
to
observe
certain safety points
<=> A-

Winter tyres
Thanks
to its
four-wheel drive, your
car
will have
plenty
of
traction
in
winter conditions, even with
•

148

Intelligent technology
the standard tyres. Nevertheless, we still recom­
mend that winter tyres or all-season tyres should
be fitted on all four wheels when winter road
conditions are expected, mainly because this will
give a better braking response.
Snow chains
On roads where snow chains are mandatory, this
also applies to cars with four-wheel drive

Opcrge
309, Snow chains.
Replacing tyres
On vehicles with four-wheel drive, all four tyres
must have the same rolling circumference. Also
avoid using tyres with varying tread depths

tapage
305,
New wheels or tyres.
Off-roader?
Some models do not have enough ground clear­
ance to be used on rough tracks and uneven ter­

rain,
so it is best to avoid off-road driving.
A WARNING
- Even with four-wheel drive, you should al­
ways adjust your speed to suit the condi­

tions.
Do not let the extra safety provided
tempt you into taking any risks when driving
- this can cause accidents.
- The braking ability of your car is limited by
the grip of the tyres. In this respect, your
car is no different from a car without four-
wheel drive. So do not be tempted to drive
too fast on icy or slippery roads just because
the car still has good acceleration in these
conditions - risk of accident!
- On wet roads bear in mind that the front
wheels may start to "aquaplane" and lose
contact with the road if the car is driven too
fast. If this should happen, there will be no
sudden increase in engine speed to warn the
driver, as with a front-wheel drive car. So do
not drive too fast in the wet: adjust your
speed to suit the conditions (accident risk).

Power management
This system helps to ensure reliable
starting

The
power management controls the distribu­
tion of electrical energy and thus helps to ensure
that there is always enough power available to
start the engine.
If
a
vehicle with a conventional electrical system
is left parked for
a
long time, the vehicle battery
will gradually lose its charge because certain
electrical equipment (such as the immobiliser)
continues to draw current even when the ignition
is off. In some cases there may not be enough
power available to start the engine.
Your vehicLe is equipped with an intelligent pow­
er management system to control the distribu­
tion of electrical energy. This significantly im­
proves reliability when starting the engine, and
also prolongs the life of the vehicle battery.
The main functions incorporated in the power
management system are battery diagnosis, re­
sidual current management and dynamic power
management.
Battery diagnosis
The battery diagnosis function constantly regis­
ters the condition of the vehicle battery. Sensors
detect the battery voltage, battery current and
battery temperature. This enables the system to
calculate the current power level and charge
con­

dition of the vehicle battery.
Residual current management
The residual current management reduces power
consumption while the vehicle is parked. It
con­

trols the supply of power to the various electrical
components while the ignition is switched off.
The system takes the battery diagnosis data into
consideration.
Depending on the power Level of the vehicle bat­
tery, the individual electrical components are
switched off one after the other to prevent the
vehicle battery from losing too much charge and
to ensure that the engine can be started reliably. •
149

Intelligent technology
Dynamic power management
While the vehicle is moving, this function distrib­
utes the available power to the various electrical
components and systems according to their re­
quirements. It ensures that on-board systems do
not consume more electrical power than is being

generated,
and thus maintains the maximum
possible vehicle battery power level.
® Note
- The power management system is not able
to overcome the given physical limits.
Please remember that the power and life of
the vehicle battery are limited.
- If the indicator lamp
|3 ^page
31 appears,
the starting ability may be impaired.
Starting ability has first priority.
Short trips, city traffic and low temperatures all
place a heavy load on the vehicLe battery. In
these conditions a large amount of power is
con­

sumed,
but only
a
small amount is supplied. The
situation is also critical if electrical equipment is
in use when the engine is not running. In this
case power is consumed when none is being
gen­

erated.

In these situations you will be aware that the
power management system is intervening to
con­

trol the distribution of electrical power.
When the vehicle is parked for long periods
If
you
do not drive your vehicle for a period of
several days or weeks, the power management
will gradually shut off the on-board systems one
by one, or reduce the amount of current they are

using.
This limits the amount of power consumed
and helps to ensure reliable starting even after a
long period. Certain convenience features, such
as remote controL unlocking, may not be availa­

ble.
These functions will be restored when you
switch on the ignition and start the engine.
150
With the engine switched off
If
you
listen to the radio or use the other info­
tainment functions when the engine is not
run­

ning,
this will discharge the vehicle battery.
The infotainment display will show a warning
message before the battery power drops to a Lev­
el where the starting ability is impaired. This
message warns you that the system you are using
will soon be switched off automatically. You
should therefore start the engine if
you
wish to
continue using the system.
When the engine is running
Although the alternator generates electrical
power, the vehicle battery can still become dis­
charged while the vehicle is being driven. This can
occur when a lot of power is being consumed but
only
a
small amount supplied, especially if the
vehicle battery is not fully charged initially.
To restore the necessary energy balance, the sys­
tem
will
then temporarily shut off the electrical
components that are using a lot of power, or re­
duce the current they are consuming. Heating
systems in particular use a Large amount of elec­
trical power. If
you
notice, for instance, that the
seat heating* or the rear window heater is not

working,
they may have been temporarily switch­
ed off or regulated to a lower heat output. These
systems will be available again as soon as
suffi­

cient electrical power is available.
You may also notice that the engine runs at a
slightly faster idling speed. This is quite normal,
and no cause for concern. The increased idling
speed allows the alternator to meet the greater
power requirement and charge the vehicLe bat­
tery at the same time.
Information saved in the
control units
The vehicle is fitted in the factory with electronic
control units that, among other things, control
the engine and the gearbox. The controL units al­
so monitor the exhaust system and the airbags.
The control units continually analyse data rele­
vant to the vehicLe while you are driving. In the •

o < 00
event of faults or anomalies in the vehicLe data,
only these data are saved. As a rule, faults are
shown by the warning lamps in the instrument
cluster.
Data saved in the control units can only be read
and analysed with special equipment.
A qualified workshop is only able to recognise
and deal with faults by using the relevant saved

data.
Among other things, the saved data may
contain the following information:
- Data relating to the engine and the gearbox
-Speed
- Direction of travel
- Braking force
- Seat belt warning system data
The control units installed will not under any cir­
cumstances record conversations in the vehicle.
Event data recorder
Your vehicLe is not equipped with an event data
recorder.
In an event data recorder, information about the
vehicle is temporarily saved. In the event of an
accident, you can therefore obtain detaiLed infor­
mation about the course of events. On vehicles
with an airbag system, accident-related data
such as impact speed, seat belt status, seat
posi­

tions and trigger times can be saved. The exact
information saved depends on the manufacturer.
The installation of an event data recorder is sub­
ject to the agreement of the vehicle's owner. This
process is governed by legislation in some coun­

tries.

Reprogramming control units
All data for controlling components are saved in
the control units. Some convenience features,
such as one-touch signalling, single door unlock­
ing and display messages can be reprogrammed
using special workshop equipment. If any
con­

venience features are reprogrammed, the infor­
mation in this Owner's Manual will no longer be
accurate for the features that have been

changed.
We recommend having the reprogram­
ming approved.
Your Audi dealer will be able to provide you with
information about possibLe reprogramming op­

tions.

Event memory
There is a diagnostic connection for reading out
the event memory Located in the
footweLL
on the
driver's side of the vehicle. Information regard­
ing the operation and status of the vehicle's elec­
tronic control units is stored in the event memo­
ry. The event memory should only be read out
and erased by
a
qualified workshop.
A WARNING
The diagnostic connection must not be used
for other purposes. Incorrect use can cause
malfunctions - risk of accident!
